400 Mm - 2000 Mm Width Cut To Length Line Machine With Hydraulic Control

3mm-12mm*2000mm cut to length machine

Product Overview

The 400 mm – 2000 mm Width Cut to Length Line Machine with Hydraulic Control is designed for processing steel coils into flat sheets with accurate length, stable surface quality, and efficient stacking.

This machine is suitable for 3 mm to 12 mm sheet thickness and 400 mm to 2000 mm sheet width. It is mainly used for cold rolled steel, galvanized steel, coated steel, and other metal coil processing applications.

The line can handle coils with 508 mm inner diameter, up to 2100 mm outer diameter, and coil weight up to 35 tons.

For steel service centers, sheet metal factories, construction material suppliers, machinery manufacturers, and industrial plate processors, this line helps convert coil material into ready-to-use sheets for cutting, welding, forming, stamping, or fabrication.

Problem

Many factories do not only need to cut steel coil into sheets. They need flat sheets with accurate length, reduced internal stress, controlled surface quality, and stable stacking.

When the material thickness reaches 3 mm to 12 mm and the width reaches up to 2000 mm, simple cutting equipment is not enough.

Common production problems include poor leveling, diagonal cutting, inaccurate length, sheet surface scratches, coil feeding instability, tail plate waste, and low production efficiency.

If the coil is heavy and thick, unstable decoiling or weak hydraulic control may also create safety risks during loading, feeding, pressing, shearing, and stacking.

The real buyer question is not only “Can this machine cut steel coil?” The better question is: “Can this cut to length line process heavy steel coils into flat, accurate, and usable sheets with stable hydraulic control?”

Cause

Cut to length production requires both strong mechanical structure and experienced process control.

First, steel coils have internal stress. If the leveling system is not strong enough, the sheet may remain wavy, bent, or uneven after cutting.

Second, thick coils require stable decoiling and pinching. If the coil head is not guided correctly, the material may feed unevenly and affect the whole line.

Third, length accuracy depends on encoder control, feeding stability, hydraulic shearing response, and electrical control coordination.

Fourth, for 35-ton coils, safety and stability are critical. The coil car, decoiler, pressing device, leveling machine, hydraulic shearing machine, and loading system must work together.

The conclusion is clear: a heavy-duty cut to length line is not just a shear. It is a complete coil processing system for decoiling, guiding, leveling, measuring, cutting, and stacking.

Solution

This cut to length line provides a complete hydraulic-controlled coil processing solution for 3 mm to 12 mm steel sheets.

The standard process can include carrying coil car, decoiler, gantry type guiding bracket, pressing device, shovel head, pair pinching rollers, three-roller first leveling, middle deviation rectification, main leveling machine, encoder, tail plate pinching, hydraulic brake type shearing machine, loading material car, hydraulic control, and electric control.

The decoiler supports heavy coil loading and continuous coil feeding. The guiding and pressing system helps introduce the coil head safely into the line.

The first leveling section helps reduce coil curvature before the material enters the main leveling machine.

The main leveling machine is the key section for sheet flatness. It corrects coil stress and prepares the material for accurate length measurement and cutting.

The encoder measures the feeding length. The hydraulic brake type shearing machine cuts the sheet according to the set length.

The hydraulic control system supports stable pressing, feeding, shearing, and material handling. The electric control system coordinates the complete production line.

Zhangjiagang Zhongyue Metallurgy Equipment Technology can customize the line according to material type, thickness, width, coil weight, cutting length, flatness requirement, workshop layout, and customer production target.

Application

This cut to length line is used in steel coil processing, sheet metal supply, machinery manufacturing, building material production, and industrial fabrication.

Steel Service Centers

Steel service centers use cut to length lines to process coils into flat sheets according to customer orders.

For this application, length accuracy, sheet flatness, production efficiency, and surface protection are important.

Construction Material Processing

The line can process galvanized steel, coated steel, and other sheet materials used in construction panels, structural parts, roofing materials, and building components.

For construction material suppliers, stable sheet size helps improve downstream forming, punching, bending, and installation.

Machinery and Equipment Manufacturing

Machinery manufacturers need flat and accurate steel sheets for frames, covers, machine bases, welded structures, and equipment parts.

For this application, leveling quality and cutting accuracy directly affect later welding and assembly.

Metal Fabrication Workshops

Fabrication workshops use cut-to-length sheets for cutting, bending, welding, stamping, and laser cutting preparation.

A stable cut to length line reduces manual handling and improves raw material utilization.

Aluminum and Stainless Coil Processing

With suitable configuration, the line can also be used for aluminum coil and stainless steel coil cutting.

For these materials, surface protection, roll design, and tension control should be discussed before final machine design.

How It Works

The production process starts when the coil is loaded onto the carrying coil car.

The coil car transfers the coil to the decoiler. The decoiler supports the coil and releases the material into the line.

The gantry type guiding bracket, pressing device, and shovel head help guide the coil head safely into the pinching roller section.

The pair pinching rollers feed the material forward. The three-roller first leveling section reduces the initial coil curvature.

The middle deviation rectification system helps correct material position before the main leveling process.

The main leveling machine corrects sheet flatness. This is the key section for reducing wave, bend, and coil stress.

The encoder measures the feeding length. When the target length is reached, the hydraulic brake type shearing machine cuts the sheet.

The cut sheet is transferred to the loading material car or stacking area.

Hydraulic control manages key movements such as pressing, shearing, braking, and material handling. Electric control coordinates the full line operation.

The key conclusion is simple: stable cut to length production depends on decoiling stability, leveling strength, accurate measuring, hydraulic shearing, and safe material handling.

How To Choose

1. Choose by Material Thickness

For 3 mm to 12 mm steel coil, the JPY3.0-12.0*1600/2000 configuration is suitable.

If the buyer processes thinner material, a high-speed light gauge line may be better. If the buyer processes thicker material, a stronger heavy gauge line should be selected.

2. Choose by Sheet Width

This product is suitable for 400 mm to 2000 mm sheet width, with the heavy-duty model commonly designed for up to 2000 mm.

Buyers should confirm the minimum and maximum coil width before selecting the machine.

3. Choose by Coil Weight

The line can be designed for coils up to 35 tons.

Coil weight affects coil car capacity, decoiler structure, foundation requirement, hydraulic system, and workshop crane selection.

4. Choose by Flatness Requirement

If the final sheet will be used for laser cutting, precision fabrication, or visible surface products, the leveling machine should be designed with higher flatness control.

For common structural sheet cutting, the flatness requirement may be different.

5. Choose by Cutting Length Accuracy

Cutting accuracy depends on feeding stability, encoder precision, hydraulic shearing response, and control system coordination.

Buyers should provide target sheet length range and tolerance requirement before quotation.

6. Choose by Material Surface

Galvanized steel, coated steel, stainless steel, and aluminum require better surface protection than ordinary carbon steel.

If surface scratches are unacceptable, roll material, guiding method, pressing pressure, and handling system should be customized.

7. Choose by Workshop Layout

The buyer should provide workshop length, width, crane capacity, coil loading direction, finished sheet stacking area, power supply, and foundation condition.

A good layout improves safety, feeding efficiency, maintenance space, and finished sheet handling.
